Dan pointed me to a quiz on distinguishing the Helvetica and Arial typefaces. I must have made a strong point of my dislike of both of them at some stage.
I did 9/10 and Steffen, a font weenie aswell, did 9/10 as well. We both failed to get the
WINDOWS example right. The capital letters just seem more similar. Perhaps the agles of the W or the roundness of the O may have have given it away. I have no way to check this though, as I have banned Arial from my computer. In fact, following the links beneath the little quiz revealed this informative article on Arial, why it is a bad idea and why Microsofts insistence to install Arial on your Mac whenever you happen to launch Internet Explorer and haven't taken countermeasures beforehand ist particularly stupid - considering that there's a perfectly good copy of Helvetica on every Mac.
